Hi every one,

I am a new member of the forum and I found the topics, questions and responses are very interesting and useful.

I am looking for the best energy conservative solution to condense a permeate stream out of a hydrophilic polymer, the permeate conditions are:

Pressure (0.01-0.1) bar
Temperature (20-50) C
Composition 95 % water vapour, 5 % a mixture of air (inert gases)
Flow rate (5-10) m3/hr

I need to condense water vapour to liquid water at minimum cost. What is the best technique and how?

Please can anyone advise me of the best available membrane software that can calculate the total energy load and cost of different scenarios of variable feed streams?

Thank you in advance for your help

I will suggest to use a barometric condenser for very low cost of operation instead of using chillers & condensers since you have only water & air as your fluid in the outlet of membranes.

thank you technologist,

dose this technology recover most of water vapor stream? and how we bring the vacuum conditions to normal? can you post the relevent links for this type of technology please as I need to estimate the cost per kL of condensed water?

regards
